Lmsdk.exe and Netwksta.exe: Programmatically Log Off Domain from Win95 and Win98

ID: Q217048

Microsoft Windows versions 95, 98

SUMMARY

This article provides a programmatic workaround for the problem described in the following KB:

Q157174 Windows NT Logon Script Does Not Run on Windows 95 RAS Client

On Win9x, if a mobile user tries to log on to a domain when the mobile machine is not connected, the user will receive the following error message:

No Domain Server was available to validate your password. You may not be able to gain access to some network resources. OK, Cancel.

If the user clicks OK and then later uses RAS to dial in to a domain, the logon script won't run because the machine assumes it has already logged on to the domain. The workaround is to call the 16-bit LAN Man API NetWkstaSetUID2 to programmatically log off the domain before using RAS to dial into the domain.

The 16-bit Microsoft LAN Manager Programmer's ToolKit version 2.1 is provided with this Microsoft Knowledge Base article for your convenience. A Visual C version 1.52 MS-DOS project demonstrating the NetWkstaSetUID2 API to log off a domain is also provided.

To use the sample, run netwks16 -d yourdomain -f 3 in an MS-DOS console window. This logs you off the domain.

NOTE: This method should be used only if you encounter the problem described in the KB article above. Furthermore, Microsoft does not recommend programmatically logging off or on to a domain, because it opens up possible security problems if the program stores and/or retrieves the password.
